APPARATUS AND METHOD FOR SPATIAL FILTERING USING ESTIMATION OF DIRECTION OF ATTENTION BETWEEN USER AND TARGET DEVICES

摘要

A spatial filtering apparatus receives a signal transmitted from a transmission terminal, and detects a synchronizing start point from a transmission frame included in the signal. When the synchronizing start point is detected, a user-defined sequence included in the transmission frame and at least one spatial random jitter beam forming (SRJBF) sequence are demodulated, and after that, a relative angle is estimated based on the demodulated user-defined sequence and the SRJBF sequence.
